Gaussian 16 is a commercial software package developed by Gaussian Inc. It is the latest version of the Gaussian series, which has been a standard tool for computational chemistry research for decades. Gaussian 16 offers a wide range of methods and tools for studying molecular structures, energies, and properties, including:
: Many supercomputing clusters, such as TACC or Lehigh University’s HPC , provide Gaussian as a pre-installed module for authorized academic users. Perfect for large-scale parallel calculations
NWChem is an open-source computational chemistry software package developed by the Pacific Northwest National Laboratory. It is designed to handle large-scale biomolecular and materials science simulations, scaling efficiently from standard workstations to massive supercomputing clusters.
Individuals can purchase licenses directly from Gaussian, Inc., though the cost is significant. Risks of "Free" Downloads
The temptation to use such sources is understandable, especially for individual researchers or small groups without institutional support. However, downloading and using pirated software carries significant risks that far outweigh any perceived benefits.
